Abstract

PROBLEM TO BE SOLVED: To make the probability of flowing-into a hit port to be fair in a prize generator by providing a structure where the running passage of a received game ball is changed by a changing member. SOLUTION: A CPU reads a random number (S101), decides which one of an appearing body or a rotary body is an object to be controlled on the basis of the random number (S102) and activates a solenoid according to the object to be controlled or controls the rotary direction of a motor (S103). Since the appearing body or the rotary body is selected at random and controlled, the appearance timing of the appearing body or the change of a rotary direction in the rotary body is never predicted. Therefore, it is not predictable whether the game ball coming into a prize generator area from a flow-in port comes into contact with the appearing body or the rotary body or not, whether the ball passes a specified passage or not and which inclining direction is obtained in the passage. That is, the running passage of the game ball which comes into the generator area is not predicted.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of a ball and ball game machine, and more particularly to an accessory attached to a ball and ball game machine.

[0002]

2. Description of the Related Art In a ball-and-ball game machine represented by a pachinko machine, a partition member for forming a role area on a game board, an entrance for flowing a game ball into a role area, and a game ball flowing into the role area are provided. Some of them are equipped with a hitting opening and a dropping-out opening, and a variable member having a variable relative position in the accessory region, and an accessory provided with driving means for driving the variable member to change the relative position.

[0003] A typical example is a central prize winning device (second type special electric accessory) of a pachinko machine called a second type. In the case of this central winning device, the course of a game ball winning from a winning opening intermittently opened and closed by opening and closing blades is changed by contact with or collision with a variable member that fluctuates regularly in the device. Then, when the game ball passes through a specific area (often referred to as V area or simply V), the operation of the opening and closing blade is continued. A game ball that has not passed through the V region is treated as a normal winning ball.

[0004] That is, whether or not the player passes through the V region is directly linked to whether or not the player can obtain more game balls, so that the operation of the variable member is important.

[0005]

However, since the change of the variable member is periodic, it is easy to be guided to the V region when winning at a specific timing, and conversely, the variable member is passed through the V region at other timings. Was almost impossible. For this reason, there is a player who fires several game balls aiming at a specific timing and does not fire the game balls at other timings and performs an irregular firing operation, which may cause trouble with the game store side.

Further, for example, there are some players who do not perform such an irregular firing operation because they do not know a suitable timing, and a known player (a player who performs variable-speed firing) and an unknown player (not performing variable-speed firing). Fairness has been impaired. Such problems are not limited to the class 2 pachinko machines, and there is a certain degree of difference in the role of the structure in which the course of the received game ball is changed by a member that periodically (regularly) fluctuates. I was

SUMMARY OF THE INVENTION An object of the present invention is to prevent the above-mentioned problems in a character having a structure in which the course of a received game ball is changed by a member that fluctuates.

[0008]

Means for Solving the Problems and Effects of the Invention According to the first aspect of the present invention, there is provided a ball game machine,
A partition member that forms an accessory area on the game board surface, an inlet for allowing game balls to flow into the accessory area, and a hit port and a disengagement port arranged to allow the game balls that have flowed into the accessory area to flow into any of them. And a plurality of variable members that can change the relative position in the accessory area, a driving unit that drives the variable member to change the relative position, and irregular control that irregularly controls the operation of the driving unit. Means.

In this accessory, an accessory area is formed on the game board surface by the partition member, and game balls flow into the accessory area from the entrance. The partition member is a member that partitions the inside and outside of the accessory area, and may be, for example, a wall-shaped member. However, since it is only necessary to make it impossible to enter and exit the game ball at a place (for example, an entrance) where the game ball enters and exits from the role area, for example, obstacle nails and pin-shaped members are arranged at intervals less than the diameter of the game ball. Or plate pieces or the like may be arranged at similar intervals. The entrance may be formed by, for example, notching a wall-shaped member, or forming obstacles, pin-shaped members, plate pieces, and the like at intervals exceeding the diameter of the game ball. In short, the partition member and the entrance only need to have a structure that does not allow the game ball to flow into the accessory area from a place other than the place set as the entrance. Note that a means for opening and closing the entrance or a means for enlarging and reducing may be provided. In addition, the entrance may be at one location or at multiple locations.

[0010] Each of the plurality of variable members has a variable relative position in the accessory area, and is driven by driving means to change the relative position. The operation of the driving means is irregularly controlled by the irregular control means. Examples of the variation of the variable member include movement along a direction intersecting with the game board surface (for example, coming and going from the game board surface), parallel movement along the game board surface, rotation or swing displacement, and the like. The driving means is not particularly limited as long as the fluctuation can be realized. For example, the driving means uses a solenoid or a motor as a driving source and drives the variable member directly or indirectly via a link or a gear.

The operation of the driving means is irregularly controlled by the irregular control means. Examples of irregular control include: making the time intervals for operating certain driving means not constant, making the directions of rotation and swinging irregular, the order of operating each driving means not periodic, and certain driving means. Irregular time intervals between the start of the operation and the start of the operation of the next drive means may be used. In short, irregular control means that the operation of the driving means is not provided with regularity or periodicity.

[0012] By such irregular control, the fluctuation of the variable member driven by the driving means becomes irregular. Then, the game ball that has flowed from the entrance into the accessory area has its course changed irregularly due to contact with or collision with the variable member that fluctuates irregularly, some flow into the hit opening, and others flow into the hit opening. It flows into the outlet.

When a game ball enters the winning opening, a condition such as a condition (or a part of the condition) may be given to give a privilege such as opening a variable winning device. On the other hand, the game ball that has flowed into the hole may be taken into the back side of the game board and treated as a winning ball, or a smaller bonus than when the ball flows into the hit hole (so-called small hit). You can also. Also,
The game ball that has flowed into the hole may not be treated as a winning ball, but may be returned to the game board from the accessory area.

Since the variation of the variable member becomes irregular, it may be irregular whether the game ball that has flowed into the accessory area enters the hit hole or not and cannot be predicted. Therefore, even if several game balls are fired at a specific timing, it is not possible to increase the probability of winning a win. In addition, the probability of winning at the winning opening does not decrease due to the timing of firing. Therefore, the irregular firing operation becomes meaningless, and fairness among players can be secured.

Are attached to the middle frame 4.

On the vertical side 2b of the hinge 3 of the outer frame 2, a lending switch 10a, a return switch 10b for inputting a return request for returning a prepaid card, and a balance display for displaying the balance of the prepaid card are provided. A CR operation panel 10 having 10c is installed.

Lending switch 10a and return switch 10
Reference numeral b denotes a switch of a type that is turned on when a pressing operation is performed and returns to off when the pressing force is released. The balance indicator 10c is composed of two 7-segment LEDs.
The segment LED can display a number from 0 to 9, and can display a two-digit number as a whole. In this embodiment, the display of the balance display unit 10c is in units of 100 yen. For example, 01 indicates 100 yen, and 10 indicates 1000 yen. In addition, each 7 segment LED is E, F,
Characters such as H and symbols that do not become characters can also be displayed.

The pachinko machine 1 has a CR unit 11.
Comes with. The CR unit 11 can take in a prepaid card inserted from the card receiving port 11a, read and rewrite recorded data, and discharge the data from the card receiving port 11a. Next, the configuration of the front side of the game board 5 will be described with reference to FIG. Two arc-shaped guide rails 19a and 19b are attached to the game board 5, and a portion surrounded by the guide rails 19a and 19b is a game area 21.

At the center of the game area 21, a central winning device 18 is provided. The outer periphery of the center winning device 18 is surrounded by a plastic peripheral wall 60 corresponding to a partition member, and the inside thereof is a role object area 62. Peripheral wall 60
An inflow port 63 corresponding to the entrance is provided at the top of the game area, and a game ball moving in the game area 21 can flow in.
A hitting opening 64 and left and right openings 65a and 65b are provided side by side at the lower part of the accessory area 62. The game balls flowing into the accessory area 62 from the inflow port 63 receive the hitting opening 64 or the opening 65a. , 65b. The game ball that has flowed into the contact opening 64 or the outgoing openings 65a and 65b passes through a guide path (not shown) passing through the game board 5,
And is treated as a winning ball. The game balls flowing into the contact opening 64 are detected by the contact sensor 18b (not shown in FIG. 2; see FIG. 4), and the game balls flowing into the contact openings 65a and 65b are detected by the contact sensor 18c.
(Not shown in FIG. 2; see FIG. 4).

In the accessory area 62, five projecting bodies 66a-6
6e and one rotating body 68 are arranged. The retractable bodies 66a to 66e and the rotating body 68 correspond to variable members. As shown in FIG. 3, the retractable body 66a penetrates a back plate 61 continuous with the peripheral wall 60, and is connected to a solenoid A as a driving means. The back plate 61 is in close contact with the surface of the game board 5. The retractable body 66a is driven in the front-rear direction by the solenoid A, protrudes to the surface side of the game board 5 when moving forward, and is housed inside the game board 5 when moving backward. Although not shown, the retractable bodies 66b to 66e are similarly driven in the front-rear direction by solenoids B to E (see FIG. 4) as driving means, respectively, and protrude toward the front side of the game board 5 when moving forward and play the game board when moving backward. 5 is housed inside. For this reason, when the retractable bodies 66a to 66e are on the forward side, the game balls falling down the accessory area 62 contact (collide) with them, but do not contact the game balls when retreating.

On the other hand, the rotating body 68 is provided with a passage 68a having a width through which a game ball can pass, and is connected to an output shaft of a motor 18a as a driving means as shown in FIG. It is driven to rotate clockwise and counterclockwise. This rotation changes the inclination direction of the passage 68a, and changes the course of the game ball that has entered the passage 68a. In addition, the course of the game ball changes due to collision with the rotating body 68.

As shown in FIG. 2, a plurality of obstacle pins 67 erected continuously from the back plate 61 are provided in the accessory area 62.
(Only a pair of so-called life nails is shown above the contact opening 64, which is shown in the figure.) The game balls change their courses even when they collide with these obstacle pins 67.

As shown in FIG. 2, below the central winning device 18, a tulip-type winning device 22 is arranged. Below the winning device 22, a big winning device 28 is installed. The special winning device 28 is provided with a special winning opening 34 that is opened and closed by the opening and closing plate 32. On the left and right of the special winning opening 34, normal winning openings 38a and 38b are provided. The inside of the special winning opening 34 is divided into a V region and a non-V region, and the special winning device 28 has a V sensor 28b for detecting a game ball passing through the V region and a winning ball to the special winning opening 34. Is provided (not shown in FIG. 2; see FIG. 4). Also,
The big winning device 28 is also provided with a solenoid 28a for driving the opening and closing plate 32 (not shown in FIG. 2; FIG. 4).
reference).

The special winning opening 34 may be opened depending on the behavior of the game ball in the central winning device 18 (details will be described later), but is normally closed. In the open state where the opening and closing plate 32 is tilted toward the front side, the special winning opening 34 is extremely easy to win. However, when the opening and closing plate 32 is set up and the large winning opening 34 is closed (closed state), the special winning opening 34 cannot be won. Become.

In the game area 21, the central winning device 1 is provided.
8 are provided with normal winning openings 40a, 40b arranged below them, ordinary winning openings 42a, 42b arranged below these, lamp windmills 44a, 44b, side decorations 46a, 46b, and an out hole 48 at the bottom. Is provided. Although not shown, well-known obstacle nails, windmills, and the like are attached to the game area 21.

The main part of the control system of the pachinko machine 1 is as shown in FIG. 4 and mainly comprises a game control device 80. The game control device 80 includes a CPU 80a, a ROM 80
b, RAM 80c, random number circuit 80d, input / output circuit (I /
O) A microcomputer provided with 80e or the like, which functions as irregular control means.

The game control device 80 includes a prize winning device 22, ordinary winning prizes 38a, 38b, 40a, 40b, 42a, 4a
2b, a winning signal from the winning sensor 50 (only one shown), a V signal from the V sensor 28b of the big winning device 28, and a 10 signal from the 10-ball sensor 28c.
A count signal or the like is input. In addition, the central winning device 18
The hit signal from the hit sensor 18b and the slip signal from the slip sensor 18c are also input. Therefore, the game control device 80 generates the winning ball, the V region,
It can know whether there is a game ball passing through a special place such as.

Further, the game control device 80 includes a solenoid 28a of the special winning device 28, solenoids A to E of the central winning device 18, a motor 18a, a firing device 51, and a payout device 52.
Are connected, and the game control device 80 can control these operations. Next, with reference to FIG. 5 and FIG. 6, control of the central winning device 18 by the game control device 80 will be described. FIG. 5 is a flowchart of the central winning device control process executed by the CPU 80a of the game control device 80, and FIG. 6 is a flowchart of the determination process. The central winning device control process is an interrupt routine that is started at an appropriate interval (in the present embodiment, approximately 0.5 seconds).
The determination process is a subroutine of a main routine (not shown) repeatedly executed by the CPU 80a at a fixed timing (for example, approximately every 2 milliseconds due to a timer reset).

As shown in FIG. 5, in the central winning device control processing, the CPU 80a reads a random number from the random number circuit 80d (S101). The random number circuit 80d is a circuit that randomly generates an integer value, and the numerical value read by the CPU 80a has no regularity. Subsequently, the CPU 80a determines which of the retractable bodies 66a to 66e and the rotating body 68 is to be controlled based on the read random number (S10).
2). In the case of the present embodiment, the remainder is 0 by dividing the random number by 7.
If it is (divisible), the retractable body 66a, if the remainder is 1, the retractable body 66b, if the remainder is 2, the retractable body 66d if the remainder is 3, the retractable body 66e if the remainder is 4, the retractable body 66e is retracted, and if the remainder is 5, the rotation is performed. Driving body 68 clockwise, remainder 6
The rotating body 68 is determined to be driven counterclockwise.

In the next step S103, if the object to be controlled determined in S102 is any of the retractable bodies 66a to 66e, power is supplied to any of the solenoids A to E to retract the same (this supply continues for a set time). If the object to be controlled is the rotating body 68, the rotating direction of the motor 18a is controlled to drive the rotating body 68 clockwise or counterclockwise (the motor 18a
Does not change until the rotating body 68 is controlled next.)

As described above, since the drive of the retractable bodies 66a to 66e or the rotating body 68 is selected at random and the drive is controlled, the timing of the emergence and retracting of the retractable bodies 66a to 66e and the change of the rotating direction of the rotary body 68 are completely anticipated. I can't get it. Therefore, whether the game ball that has flowed into the accessory area 62 from the inflow port 63 comes into contact with any of the retractable bodies 66a to 66e, contacts the rotating body 68, or does not pass through the passage 68a of the rotating body 68, The inclination direction of the passage 68a at that time cannot be predicted. Therefore, the accessory area 62
Game ball that has flowed into the hole 64 or hits the opening 64
It is also irregular to enter the balls 5a and 65b and cannot be predicted.

In the pachinko machine 1 of the present embodiment, the contact opening 64
A bonus is given to the player when the player enters the ball, so that point will be described with reference to FIG. As shown in FIG.
The PU 80a determines whether or not a game ball has entered the hit port 64 based on whether or not a hit signal from the hit sensor 18b has been input (S201).

If the ball has entered the contact opening 64 (S20)
1: YES), the payout device 52 is instructed to pay out the set number of prize balls (for example, 10) (S2).
02), start a special game (S203), and return. The control relating to the execution of the special game is a special game control process (not shown) as a subroutine of the main routine.
It is executed in. The special game in this embodiment is similar to the special game in the publicly known type 1 pachinko machine (commonly a fever machine). Briefly, the game control device 8
A value of 0 activates the solenoid 28a of the special winning device 28 to open the special winning opening 34. This opening is continued for about 30 seconds or until ten game balls are detected by the ten ball sensor 28c. Then, if there is a game ball that has passed through the V area during the opening period (if the game ball is detected by the V sensor 28b), the special winning opening 34 is opened again. However, in the case of the present embodiment, the number of times of opening the special winning opening 34 (so-called round number) does not exceed 10 times. In addition,
If there is a new ball in the hit port 64 during the preceding special game, the preceding special game is ended there (1).
This is a setting in which the game is terminated even if the round has not reached 0) and a new special game is started.

On the other hand, if the ball has not entered the hitting port 64 (S201: NO), the game ball enters one of the opening ports 65a and 65b depending on whether or not a disconnection signal from the disconnection sensor 18c has been input. It is determined whether or not the ball is hit (S2
04). If the ball has entered the opening 65a, 65b, the payout device 52 is instructed to pay out the set number of prize balls (for example, 10) (S205), and the process returns.
If the ball has not entered the outgoing holes 65a and 65b, the process returns without performing any substantial processing.

As described above, when the ball enters the contact opening 64,
As a special game is executed as a special benefit,
Whether or not to enter 4 is of great concern to the player. However, as described above, since the behavior of the retractable bodies 66a to 66e, the change in the rotation direction of the rotating body 68, and the like are completely random, the game ball flowing from the inflow port 63 to the accessory area 62 hits in any route. Mouth 6
It is not possible to predict whether it will be 4 or the openings 65a, 65b. Further, the game balls flowing into the accessory area 62 from the inflow port 63 at a specific timing do not easily enter or hardly enter the hit port 64.

Therefore, even if several game balls are fired at a specific timing, it is not possible to increase the probability of entering the hit port 64. In addition, the probability of entering the hitting opening 64 does not decrease due to the timing of firing. Therefore, the irregular firing operation becomes meaningless, and fairness among players can be secured.

Although the embodiments of the present invention have been described according to the examples and the modifications, the present invention is not limited to these examples.
